NUT-LOCK.

Be it known that LALvIs J. HATHOOX, a citizen of the United States,residing at of Oklahoma, have invented certain new and usefulImprovements in Nut-Locks; and I do declarethe following to be a full,clear, and exact descriptionofthe invention, such as will enable otherskilled in the art to which it appertainsto make and use the Thisinvention relates to improvements in nut locks and has for its objectsthe production jofa simplenut lock comprising a longitudinally splitbolt and a washer and a nut arranged on 'the bolt having clutchsurfaces, the washer being provided with an overhanging locking armadapted to enter this split portion of the bolt.

With the foregoing and other objects in arrangement of parts, as will bemore fully described and particularly pointed out in the appended claim.

' In the accompanyingdrawings, Figure 1, is a side elevation with thearm of the washers'hown in operative position. Fig. 2, is a plan viewthereof.

Referringto the accompanying drawings,

4 of the washer 3. The washer 3 is preferably made of malleablejiron orother metal 5 and before being applied on the bolt, the locking arm orkey 5 is extended in a line substantially parallel with the axis of thebolt. In assembling the lock the washer 3 is locking key in a positionat right angles thereto, and'the nut threaded on the split Patented June1, 1909.

end of the bolt with the clutch teeth 7 facing inwardly and forcedagainst the clutch teeth a of the washer 3. When the nut 6 has beenforced to its innermost position against the washer 3, the outer end ofthe locking arm or key 5 is bent over the nut 6 and said end forcedbetween the split end of the bolt 1 and hammered against the outer sideor face of said nut.

By means of my improvements a nut lock is provided which will withstandsevere stress and securely clamp a rail or other device. It will beobserved that when the locking arm or key 5 has been forced. between thesplit end of a bolt 1 and against the outer side of the face of the nut6, said nut will be confined between the outer face of the washer 3 andsaid arm and the teeth 7 of the nut will be held in positive engage mentwith the teeth i of the washer, so as to permanently confine and holdthe nut and the washer on the outer end of the bolt.

In applying my invention the slot of the threaded bolt is preferablyformed just deep enough to receive the locking arm or key of the washer,but the depth of the slot will of course be regulated by the conditionof the work. The washer arm is formed with a suitable taper so that itmay readily enter the bolt slot.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.
